- To create a more sophisticated document, you DEFINE
- VARIABLES and COMPUTE RESULTS based on those variables.
- For example:
- .TXT 4 0 1 22
- 1,22
- Define a,b,c ───
- .EQN 0 26 1 8
- ! rd=d ct=10 im=i et=3 zt=15 pr=3 mass length time charge
- a:2
- .EQN 0 10 1 8
- b:3
- .EQN 0 11 1 8
- c:1
- .EQN 1 -21 5 23
- x:(-b+\(b^2-4*a*c))/(2*a)
- .TXT 3 -26 1 22

- Define x ───
- .TXT 3 0 1 22
- 1,22
- Show value of x ───
- .EQN 0 26 1 12
- x=-0.5?
- .EQN 2 0 2 19
- a*x^2+b*x=-1?
- .TXT 1 -26 1 22

- Compute with x ───
- .TXT 2 0 2 47
- 2,47
- If we change a, b, or c, the value of x will
- change. Watch as we change the value of c.
